Description

INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS Any and all applications, if any, for which a foreign or domestic priority claim is identified in the Application Data Sheet of the present application are hereby incorporated by reference under 37 CFR 1.57. FIELD The present disclosure relates to the field of patient monitoring. More specifically, the disclosure describes, among other things, devices, systems, and methods for monitoring and/or displaying information regarding a patient's position, orientation, and/or movement in a medical environment, and an improved graphical user interface. BACKGROUND In clinical settings, such as hospitals, nursing homes, convalescent homes, skilled nursing facilities, post-surgical recovery centers, and the like, patients are frequently confined to a bed for extended periods of time. Sometimes the patients are unconscious or sedated to such an extent that they have limited ability to change or control their position and/or orientation in the bed. Such patients often require assisted breathing apparatuses and, for example, may be intubated with an intubation tube. Maintaining proper airflow through an intubation tube may require correct positioning of the intubation tube and/or proper positioning of the patient to prevent inhibited airflow through the intubation tube that may develop as the result of deformation in the tube. Such patients can also be at risk of forming pressure ulcers, which pose a serious risk to the patient's health and well-being. Pressure ulcers, which may also be referred to as “bed sores,” “pressure sores,” and “decubitus ulcers,” involve injury to a patient's skin, and often the underlying tissue, which results from prolonged pressure forces applied to a site on the patient's body. Frequently, pressure ulcers develop on skin that covers bony areas of the body which have less muscle and/or fat tissue below the surface to distribute pressure applied thereto. Pressure ulcers can develop when such skin is subjected to prolonged contact with a surface of a bed or chair. Examples of such body locations include the back or side of the head, shoulders, shoulder blades, elbows, spine, hips, lower back, tailbone, heels, ankles, and skin behind the knees. Pressure ulcers are caused by application of pressure at an anatomical site that occludes blood flow to the skin and other tissue near the location. Sustained pressure between a structural surface (such as a bed) and a particular point on the patient's body can restrict blood flow when the applied pressure is greater than the blood pressure flowing through the capillaries that deliver oxygen and other nutrients to the skin and other tissue. Deprived of oxygen and nutrients, the skin cells can become damaged, leading to tissue necrosis in as few as 2 to 6 hours. While hospital-acquired pressure ulcers commonly occur in elderly and mobility-impaired populations, such ulcers are considered to be preventable and have been termed “never events.” In some cases, medical insurance carriers have imposed restrictions on the amount they will reimburse a hospital for pressure ulcer treatment, and state and federal legislation now requires hospitals to report the occurrence of pressure ulcers in their facilities. Risk factors for pressure ulcers can be categorized as modifiable and non-modifiable. Modifiable risk factors include actions that healthcare providers can take, while non-modifiable risk factors include aspects of patient health and behavior. It is valuable to document such non-modifiable risk factors so that caregivers can identify and attend to patients at risk of developing pressure ulcers. It is recommended that caregivers develop a documented risk assessment policy to predict the risk of a patient developing a pressure ulcer. Such an assessment can encompass all aspects of a patient's health and environment, and may employ commonly used measures in the field, such as the Braden and Norton scales. Such risk assessment tools may be used to direct preventative strategies not only when a patient is at rest in his or her bed, but also when undergoing surgery. Additional factors that can contribute to the formation of pressure ulcers include friction and shear forces. Friction can occur when skin is dragged across a surface which can happen when patients are moved, especially when the skin is moist. Such frictional forces can damage the skin and make it more vulnerable to injury, including formation of a pressure ulcer. Shear forces occur when two forces move in opposite directions. For example, when the head portion of a bed is elevated at an incline, the patient's spine, tailbone, and hip regions tend to slide downward due to gravity. As the bony portion of the patient's body moves downward, the skin covering the area can stay in its current position, thereby pulling in the opposite direction of the skeletal structure. Such shear motion can injure the skin and blood vessels at the site, causing the skin
